We use Q345B or ASTM A572 Grade 50 structural steel, which offers excellent strength-to-weight ratio. All surfaces undergo:
Shot blasting
Hot-dip galvanization (minimum 85µm coating)
Optional powder coating for harsh climates
This ensures long service life in coastal areas of Southeast Asia or high-humidity regions like the Congo Basin. Our bridges typically have a lifespan of 25–50 years with minimal maintenance.
